Summary

In this chapter, we finalized our FTP server. Then, we learned how to do different types of tests. We saw how we can test a single function or type by writing unit tests. We learned how to test a program as a whole by writing integration tests. We also learned about documentation and fuzzing tests to make sure our examples are up to date and to find even more bugs in our application.

In the next and ultimate chapter, we will learn about Rust's good practice and common idioms.
